Educating India’s Farmers in New Farming Practices:A New Initiative

Regardless of the adoption of new crops, old and outdated farming practices result in a high rate of crop disease, which affects the standard of living of the farmer and their families.

SRIJAN, a leading education resource in India, seeks to introduce new farming practices that encourage:

 Sustainable use of land free from over-farming.
The use of irrigation techniques to ensure sustainable land use, especially in a changing climate.
The adoption of new farming techniques and new crops to create revenue growth for farmers.

In pursue of the third goal, SRIJAN encourages the adoption of best farming practices in Soy crop. Both state and federal government bodies also encourage it through their extension system, but their programs aren’t that effective due to well known reasons such as lack of motivation and lack of coordination with research institutions.
When in comparison to maize and bajra (millets), soy can result in more than Rs. 2,000 – 3,000 more per acre of land. In some cases, soy can be grown at the same time as other crops, further increasing the revenue potential for the farmer. Soy can often be a cash earner for a farmer while the other crops are used for family subsistence. A growing market for soy products includes soy oil, soy meal and nutrinuggets. Soy oil cakes can also be used for animal fodder.

SRIJAN’s current outreach is 800 soy farmers, likely to go up to 3000 next year, and 10000 in three years.

Challenge would be, on the one hand, to transfer maximum information (audio-visual, audio, visual, text, in that order) and to enable maximum interaction with the farmer at least cost. And on the other, it should be a micro-enterprise opportunity for youth.

Farmers are apprehensive about adopting new farming practices or crops. This is largely based upon an adherence to tradition, sometimes dating back several generations. Farmers must be shown proof that new practices will result in a better standard of living before they risk their family’s wellbeing – which is often directly influenced by their crop yield. As such, the major challenge for the adoption of new practices is one of education and trust.

An opportunity exists to employ local youth to help build this trust. Often youth are attracted to job opportunities in urban centers only to be

disappointed by the dismal living conditions and eventual decrease in living standards. In order to prevent this “brain drain” and, at the same time, reform farming practices, some youth can be encouraged to start a business that sells services to local farmers. Using a standard camera cell phone (already common among rural youth), a businessperson can take pictures of diseased crops and upload that information to a center for analysis. That analysis and information about solutions to treating crop disease can be shared with local farmers, thereby building trust and dependence.

This trust can be translated into additional service opportunities, such as the promotion of new crops, soil testing facility, hybrid seed production, and the lending of farming equipment (new plows, safer pesticides, etc.). Local youth can engage in “co-operation” type arrangements where best practices can be shared amongst them to increase the overall yield of farmers within a larger area. SRIJAN promotes farmers groups (particularly of women farmers who are often illiterate). Technologies such as a standard cell phone, crowdsourcing and wellorganized database about local farming conditions can serve to enable these young entrepreneurs (including literate young daughters in-law) to effective contributors to their local society.

In this model, the youth are employed and earn money while farmers invest to increase their crop yield and their profits. What works for Soy, could work for pomegranate, millets, and paddy as well.

Lessons American and Schools All Over The World Can Learn from China

Guest Post by Kaitlyn cole

In a survey from the OECD Programme for International Student Assessment (PISA), it was revealed that Chinese students are easily outperforming their peers around the world. For anyone familiar with the “Tiger Mother” parenting style of Amy Chua, this is certainly not a surprise. It is a disappointment for American students, however, who no doubt would like to be superior as well. But the fact remains that the Chinese are simply outperforming the rest of the world, and it has little to do with natural ability or even luck, but rather, smart choices made in the educational culture in China. Read on, and we’ll take a look at 10 things that China is doing that make a difference in their educational performance, as well as consider how these ideas might be applied to American education.

 Education is a top priority

One of the biggest things American schools can learn from Chinese education is that learning is simply one of the most important things in China. The entire country has a drive to do better and learn more, motivated to continue to grow as a superpower, and pushing each new generation to become smarter, more productive, and more innovative than the last. And while the American government pays lip service to education at the federal, state, and national level, China actually makes education one of its top priorities. According to the New York Times, there is a “Confucian reverence for education that is steeped into the culture,” where teachers are highly respected, and class clowns and jocks play second fiddle to the smartest kid in the class. There is a real passion for learning in the Chinese education system, in stark contrast to American schools which often get caught up in teaching to the next goal, typically for standardized tests. The Chinese model of celebrated education is one that’s hard to quantify, but US schools can take a lesson from an education system that makes it cool to be the smart kid.

 China is cutting out college majors that don’t pay

Both the US and China are having a problem with jobless graduates, but China is doing something serious to stop it: the Ministry of Education recently announced that they would phase out majors that produce unemployable graduates. The government will systematically evaluate college majors by their employment rates, and subsequently downsize or completely cut out studies that produce employment rates below 60% for two consecutive years. Although some laud the idea as an efficient way to produce college graduates who will become employable and productive, many university professors are not happy with the idea, as they worry that the downsizing may cut out subjects, like biology, that are not currently strong in the market, but nonetheless necessary to China’s mission for leadership in science and technology. But this is not a new idea, anyway: according to the Wall Street Journal, universities have been downsizing programs that don’t result in paid positions, with China’s Shenyang Normal University cutting its Russian program from 50 to 25. If the US government followed the Chinese approach, majors that would be cut include psychology, US history, and military technologies.

 Teachers are retrained before being dismissed

Teacher turnover is expensive and disruptive, plain and simple. In a study from the National Commission on Teaching and America’s Future, it was revealed that for each teacher turnover, schools lose about $9,500 in costs, including training, administrative processing, and recruitment. That’s a significant number for each teacher that is fired or walks out the door due to dissatisfaction. But perhaps worse than the financial impact of teacher turnover is the educational fallout as teachers are first ineffective, and then not there at all. Students are further inconvenienced as a new teacher is hired and brought up to speed, while weeks of curriculum may fall by the wayside. Rather than allow students and educational budgets to suffer from the dismissal of poorly performing teachers, Chinese administrators choose to retrain existing teachers, working to improve their skills and abilities so that they may remain in their position while doing a significantly better job. Certainly not all “bad” teachers can benefit from training instead of dismissal, and some must eventually be fired, but by offering teachers the opportunity and resources to create improvement, China saves not just money, but the time and attention of the students served by challenged teachers.

 Education spending is growing

The US spends more per GDP on education than China, with 5.7% GDP to China’s 2.5%. Still, critics believe that China has learned how to spend its small budget wisely, pointing out that while previously, China did not have the bureaucracy to ensure money was spent correctly, the country has now shifted delivery of social services to the county level where personnel are better trained. And as the country as a whole better learns how to spend its meager education budget, that budget is also growing: Chinese education spending has grown by 20% every year since 1999, now reaching more than $100 billion. Meanwhile, education spending in the US has grown at a much slower pace: in recent years, spending has risen by a meager 5.8%. This indicates that while the US remains stagnant in its education growth, China is and has been making a great effort to push for more education funding and better schools.

China increased teacher pay and training to success

In response to the Programme for International Student Assessment (PISA) comparative survey, Time took a look at China’s educational approach and the latest education reforms in the country, reporting that much of the country’s latest success goes to “significantly increased teacher pay and training,” and that this is among the lessons that can be learned from high performing Shanghai and Hong Kong. This lesson is so painfully obvious, but it’s worth pointing out: better teachers can create better students. Giving teachers the tools and motivation they need to do a great job can and will pay off in smarter students, as evidenced by China’s great performance in the PISA.

Reduced emphasis on rote learning, more problem solving

Another lesson that Time reports we should take away from China’s great showing in the PISA is the “sea change in pedagogy,” which takes the emphasis that used to be directed to rote learning, and instead focuses on learning more about problem solving. One new slogan promises, “To every question there should be more than a single answer.” This type of learning is something that a lot of American students don’t see until they get to college, if at all. Dismissing rote learning for problem solving allows Chinese students to learn how to learn, rather than how to memorize, a valuable skill that undoubtedly serves them well in today’s culture of ubiquitous information. The American school system can make a different by following China’s lead and forget about “teaching to the test” and forcing students to memorize facts that they can Google in seconds, and instead develop minds that are more adept at learning how to solve problems.

 Non-attentive students are not tolerated

China’s educational culture places great value on hard work and dedication, and students are expected to care about their studies. Experts report that non-attentive students simply aren’t tolerated. It sounds harsh, but students that don’t pay attention can be a real problem in the classroom. By not allowing them to be disruptive, Chinese classrooms benefit from them not being able to interrupt or slow down the entire class, much to the detriment of other students. Perhaps the only place where American students can see this sort of streamlined studying is in advanced or AP classes, in which high achieving students presumably want to be an active participant in their studies.

Extracurricular activities are downplayed in favor of more studying

The Atlanta Journal-Constitution describes the Chinese model of education as a “no-frills, academic-focused approach that will likely seem grim to many US parents.” But one of the major lessons from China’s excellent educational performance is that they push for “less sports and more studying,” putting extracurricular activities on the back burner in favor of quantifiable learning. And although parents in the US are likely to ask for more arts classes, China’s rigorous model of education still allows them to outperform the world. It’s not likely to happen in America, but the fact is simple that by sacrificing time in music, art, drama, and sports, students are able to spend more time focusing on core basics, and thus perform better in those subjects.

Chinese students spend more time in school

American students go to school somewhere in the neighborhood of 8AM, just like Chinese students, but unlike Chinese students, they are typically out of school by 4PM, with an average seven- to eight-hour day. At 4PM, Chinese students still have four more hours to go, as their school day lasts not from 8AM to 4PM, but goes on until 8PM, with 12 hours in school each day. Not only that, Chinese students typically have 43 more school days each year than American Children do. This all results in significantly more class time, time in which Chinese students are learning the curriculum that American students simply didn’t have enough time or days to get to. Although American students aren’t likely to tolerate a 12-hour school day five days a week, parents and students alike might benefit from a schedule that more closely models the typical parent work day of eight to ten hours, as well as calendar schedules that allow for fewer days out of school, which can make the difference between missed instruction opportunities and students who have fully learned the material at hand.

 Recruiting and keeping key educators

While American schools allow great talent to walk right out the door in favor of higher pay in other professions or private schools, the Chinese recognize the value in recruiting professionals who can do a great job with their students. In fact, according to the Standard Speaker, the Chinese government has people on its payroll whose sole purpose is to actively find and recruit people, particularly educators, from all over the world, including the US, to bring to China to help prepare their students for the global market. This not only puts China at an advantage with great talent, it creates a “brain drain” in the US and other countries as we lose valuable talent to China. America would do well not only to recognize key educators, but to reward them for their value, and even do some of its own international recruiting that can attract top educational talent to the US.

India’s Green Revolution Over?

Farmers in the village of Chotia Khurd in northern India don’t realize it, but they symbolize a growing problem that could become a global crisis.

They gathered on a recent morning in a stone-paved courtyard — a circle of Sikhs with brightly colored turbans and big, bushy beards — to explain why the famed “bread basket” of India is heading toward collapse.

Their comparatively small region, Punjab, grows far more wheat and rice for India than any other region. But now these farmers are running out of groundwater.

They have to buy three times as much fertilizer as they did 30 years ago to grow the same amount of crops. They blitz their crops with pesticides, but insects have become so resistant that they still often destroy large portions of crops.

The state’s agriculture “has become unsustainable and nonprofitable,” according to a recent report by the Punjab State Council for Science and Technology. Some experts say the decline could happen rapidly, over the next decade or so.

One of the best-known names in India’s farming industry puts it in even starker terms. If farmers in Punjab don’t dramatically change the way they grow India’s food, says G.S. Kalkat, chairman of the Punjab State Farmers Commission, they could trigger a modern Dust Bowl. That American disaster in the 1930s laid waste to millions of acres of farmland and forced hundreds of thousands of people out of their homes.

The story of Chotia Khurd is a cautionary tale: Political leaders and scientists can’t necessarily transplant a technology from one country and culture to a vastly different one and expect it to flourish without serious side effects.

The ‘Green Revolution’

The story begins in the 1960s, when parents in America’s well-fed suburbs would admonish ungrateful children to “think about the starving people in India.” Occasional news reports told wrenching stories about Indians subsisting on grass and leaves. The country survived on imports, like a beggar.

The public concern prompted a loose coalition of scientists, government officials and philanthropists — spurred and funded, in part, by the Rockefeller Foundation —to launch a “Green Revolution.”

In the context of the times, “green” did not refer to what it means today — organic, pesticide-free farming methods. To the contrary, India’s farmers were persuaded to abandon their traditional methods and grow crops the modern, American way.

For example, the advisers told farmers to stop growing old-fashioned grains, beans and vegetables and switch to new, high-yield varieties of wheat, rice and cotton. Farmers began using chemical fertilizers instead of cow dung. They plowed with tractors instead of bulls.

The “Green Revolution” of the 1960s and 1970s meant that if farmers embraced chemicals and high-yield seeds, their fields would turn lush green with crops. (An official at the U.S. State Department, William Gaud, apparently coined the term in 1968.)

During the Cold War, the term also implied that if countries like India could stamp out hunger, the population would be less likely to foment a violent revolution and go communist.

A Temporary Fix

In India, ground zero for the Green Revolution was the state of Punjab, which borders Pakistan and the foothills of the Himalayas. And the system seemed to work miracles — for a while.

The United States sent money and technical support, including advisers from one of America’s most prestigious agriculture universities. India’s government showered Punjab with low-cost chemicals and seeds — and they paid the farmers, in effect, to use them by guaranteeing minimum prices for Green Revolution crops.

It helped India transform itself from a nation that depends on imports and food aid to a budding superpower that often exports grains.

Villages like Chotia Khurd were harvesting three to four times as much grain per acre as they did before.

Many of the farmers and the local government were flush with money. They paved their dirt roads. The farmers replaced their mud houses with bricks and cement. They bought American tractors for a small fortune.

Just about everybody in Chotia Khurd bought cell phones, with a wide variety of ring tones — so it’s hard to chat with a farmer without getting interrupted by electronic versions of Sikh chants or theme songs from Bollywood hits.

But government reports and farmers themselves say that era is over — and today, the Green Revolution system of farming is heading toward collapse.

‘Farmers Are Committing A Kind Of Suicide’

To show why, the district director of the Punjab Agriculture Department, Palwinder Singh, leads the way up a narrow dirt road into wheat fields that encircle the village.

On the surface, they look robust. The countryside is electric green in every direction.

But Singh points to a large contraption rising above the crop, like a steel praying mantis. The machine is blanketing the countryside with a percussive, deafening roar.

“That’s part of our most serious problem,” he says. It’s a drilling rig. A young farmer in a purple turban, Sandeep Singh, is standing next to the rig, looking unhappy. (The two men are not related — according to tradition, all Sikh men share the last name “Singh,” which means “lion.”)

When farmers switched from growing a variety of traditional crops to high-yield wheat and rice, they also had to make other changes. There wasn’t enough rainwater to grow thirsty “miracle” seeds, so farmers had to start irrigating with groundwater. They hired drilling companies to dig wells, and they started pumping groundwater onto the fields.

But Sandeep says he has been forced to hire the drilling company again, because the groundwater under his fields has been sinking as much as 3 feet every year.

Government surveys confirm it. In fact, his family and other farmers have had to deepen their wells every few years — from 10 feet to 20 feet to 40 feet, and now to more than 200 feet — because the precious water table keeps dropping below their reach.

Nobody was surprised when environmental activists started warning years ago that the Green Revolution was heading toward disaster. But they were astonished as government officials started to agree.

“Farmers are committing a kind of suicide,” warns Kalkat, the director of the Punjab State Farmers Commission. “It’s like a suicide, en masse.”

Kalkat offers an unsettling prediction in a nation whose population is growing faster than any other on Earth: If farmers don’t drastically revamp the system of farming, the heartland of India’s agriculture could be barren in 10 to 15 years.
